Answer:

22 square millimeters

Step-by-step explanation:

Given,

Parallel sides of the trapezium = 3mm, 8mm

Height of the trapezium = 4mm

Therefore,

Area of the trapezium

[tex] = \frac{1}{2} \times (sum \: of \: parallel \: sides) \times height[/tex]

[tex] = \frac{1}{2} \times (8 + 3)mm \: \times 4mm[/tex]

[tex] = \frac{1}{2} \times 11mm \times 4mm[/tex]

= 11mm × 2mm

[tex] = 22 {mm}^{2} [/tex]

Hence,

Area of the trapezium is 22 square millimeters (Ans)
